Lamp design ideas

[H_J_vanAndel]

Hi Readers, 

I'm trying to replicate something like the attached image in F360. 

 

I'm doing the baseshape with Sculpt, but looking ideas on how to apply the sinuslike wave along the outside of the surface as efficiently as possible. 

I have my base shape a little different than the picture,  4 circles instead of the spline section from the example lamp. I'm than  adding another circular pattern on top of this. Extruding the result and adding fillets to the sharp corners to add the waves, but I'm feeling this could be done more efficiently. (Example image from AutoCAD as I'm typing this from my work laptop without Fusion available). 

 

 Ideas on how to loft/sketch/sweep the baseshape are welcome as well to further parametrize the sketch, but for now I would be ok with using sculpt on this as the first prototype.

Simplify your sketch.

Pattern Features (or Faces) rather than sketch elements.

Do you have any examples of prior work you have completed in Fusion ranging from the simple to moderately complex that you can Attach here.

Or is this your first Fusion project?

I'm quite new to Fusion 360 (2 weeks) and especially the lamp and charging dock I know are not optimal, as it was also a bit of a "process" going through them, so some of the model additions are not always in the most logical order. 

- Lamp was my first "bigger" project, before this I mostly made some small candle lights with spirals etc. using intersects. 

- Charging Dock was the project after Lamp. 

- Wavy is a vase/lampshade in progress which works ok because it has no rotation.  It could probably do with a similar optimization as I'm asking for the example given in my first post here. 

I do have Inventor experience, but at our company there is a philosophy to add as many features in a sketch to make them traceable and modifyable more easily, which is a bit different than the Fusion 360 advised approach. (+ that's it been a few years since I last used Inventor as well as I changed functions within the company).

Nope.  Geometry is geometry - complicated sketches are the wrong technique in any parametric history-based MCAD software.

I understand your statement, and we know it has it's disadvantages, but it's a method I've come across more companies than just our own in the Netherlands in the heavy mechanical industry, I guess it's just something that works when trying to keep multiple people in a team working a similar way. But that's deviating from the home decoration F360 / 3d printing subject 😅

Looking at your files it appears that you have a pretty good handle on the basics (other than some unconstrained white dot endpoints and blue lines).

Unfortunately I have to get some other work done at the moment.

I'm sure one of the experts here will jump in and offer assistance.

If I add my apprentice years as an industrial mechanic (before college) to it I am approaching 40 years of experience in manufacturing. I created technical manufacturing drawings with pencil/paper/ink before computers became prevalent.

I stared with CAD during my university years and have worked with cad and other 3D modeling and rendering applications professionally as a degreed engineer for over 3 decades. I started with 3D CAD (SolidWorks) in 1998.

Those "traditional" workflows are simply out-of-date an date back to a time and habits that were developed before modern parametric solid modeling tools were available.
